What is connected to these ports?
It would appear that the connected devices either have their MTU's set to greater than 1,500, or they have jabbering interfaces (which seems unlikely).

Yes, still convinced something in the chain isn't happy with the MTU being used. Check everything that is connected to the switches, also possible virtual systems ...

There's a lot a VM's on the network using those interfaces and associated port channels. So I need to verify every device and VM using those interfaces and port channels?

How would I determine what to increase the mtu to? I would still need to determine what the mtu for the VM's are, correct?

Ok. Thanks for the tips.

Last question, how do I determine the error rate and what rate is above the acceptable rate for input errors and CRC errors?

for TenGigabitEthernet2/3 the input error rate would be 62641 divided by 14130000 which is 4.433 %??????
